    Freely Tunable Dual-Passband Microwave Photonic Filter Based on Phase-to-Intensity Modulation Conversion by Stimulated Brillouin Scattering

    Freely Tunable Dual-Passband Microwave Photonic Filter Based on Phase-to-Intensity Modulation Conversion by Stimulated Brillouin Scattering by Zhen Zeng, Zhiyao Zhang, Zhengkai Li, Jun Yuan, Shangjian Zhang, Yali Zhang, Zhengping Zhang, Yong Liu

    Published 2019-01-01

    An approach to achieving a highly selective and stable microwave photonic filter (MPF) with two passbands independently tunable is presented. The dual-passband MPF is realized based on phase-to-intensity modulation conversion by stimulated Brillouin scattering. In the proposed scheme, a freely tunab...

    Optically Tunable Microwave Frequency Downconversion Based on an Optoelectronic Oscillator Employing a Phase-Shifted Fiber Bragg Grating

    Optically Tunable Microwave Frequency Downconversion Based on an Optoelectronic Oscillator Employing a Phase-Shifted Fiber Bragg Grating by Yangxue Ma, Zhiyao Zhang, Jun Yuan, Zhen Zeng, Shangjian Zhang, Yali Zhang, Zhengping Zhang, Dongbing Fu, Jianan Wang, Yong Liu

    Published 2018-01-01

    We demonstrate an approach to achieve optically tunable microwave frequency downconversion based on an optoelectronic oscillator (OEO) incorporating a tunable microwave photonic filter. The wideband tunable local oscillation (LO) is generated in the OEO through simply tuning the frequency difference...
